High-quality whispering-gallery-mode optical resonators have garnered interest in particle sensing for a variety of applications. Here, we further explore the idea of using microresonators to enhance single-particle detection and identification by monitoring the Raman scattering from a particle adhered to a silica micro-sphere. A tunable diode laser is critically coupled into a resonant mode of the micro-sphere resonator, allowing circulating power to build up within the cavity for enhanced interaction with the attached particle. Experimental results of single particle Raman scattering in microsphere resonators are presented.
